How do you keep your water and food (water in particular) clean? The waterer in our brooder is off the ground about 6-8 inches, but the water still gets murky/dusty within a half day. We have a 3 gallon waterer and 11lb hanging feeder for our coop which we'll move our chicks out to in a couple weeks. We are planning to keep them in the henhouse. I'd love to hear any suggestions you have.
